Review for Giro Women’s Sonnet Cycling Helmet – 2018

The Sonnet is a favorite in our Women’s Series collection, offering acclaimed fit and performance for riders who enjoy great routes as much as a swift pace. The slim shape offers great ventilation thanks to 25 Wind Tunnel vents and the comfortable convenience of the adjustable Roc Loc 5 fit system. And with the light weight and durability of In-Mold construction, it won’t weigh you down. Sonnet MIPS models are available with the Multi-Directional Impact Protection System. We believe MIPS can redirect energy and provide more protection in certain impacts.WOMEN’S SERIESThe Women’s Series is a diverse collection of helmet styles, fits and prices tailored to the demands of female riders. While the level of detail and range of colors is unique within the Women’s Series helmets, they do not feature a unique “women’s fit.” That’s because there is no anatomic difference between women and men’s heads except for the average skull diameter measurement. And since Giro helmet sizes cover 98% of the human population, we believe the Women’s Series offers more options to women than any other brand.WIND TUNNEL VENTILATIONGiro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride.SUPER FIT ENGINEERINGOur proprietary Super Fit sizing system is based on “human scale factors” data and over 25 years of handcrafting helmets. By creating helmet molds in up to 4 adult sizes to match the human body’s form, our Super Fit sizes comfortably and securely fit riders, and feel like they are custom made just for you.ROC LOC 5 FIT SYSTEMThe industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.IN-MOLD CONSTRUCTIONIn-Mold Construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.SUPER FIT SIZES: S 20″-21.75″, M 21.75″-23.25″ Ponytail compatible 25 Wind Tunnel vents with internal channeling Roc Loc 5 fit system In-mold polycarbonate shell with EPS liner
